AM Learning Zone

Spot the Early Signs of
Alpha-mannosidosis

Alpha-mannosidosis is ultra-rare, but its impact is profound. Delays in diagnosis are all too common, caused by the broad variability of symptoms and their similarity to other pediatric conditions. The AM Learning Zone helps healthcare professionals think rare, recognize early signs, and act faster—transforming outcomes with earlier, more accurate referrals and care.

Recognizing AM

Alpha-mannosidosis (AM) is a rare autosomal recessive lysosomal storage disorder caused by deficient acid alpha-mannosidase activity, which allows mannose-rich oligosaccharides to accumulate and affect multiple organ systems over time. Its severity varies widely by phenotype, and its early features overlap with far more common childhood presentations.

Think Alpha-mannosidosis

Early signs — recurrent ear and respiratory infections, hearing loss, coarsening facial features, and developmental delay affecting speech, cognition, or motor skills — are typically managed in isolation across different specialties. Thinking AM means recognizing these as facets of one underlying condition rather than separate problems, even when the overall picture appears mild.

Act Early

Because presentation varies and the early signs are nonspecific, AM is often diagnosed only after years of separate referrals. Once it is suspected, an enzyme assay for acid alpha-mannosidase or MAN2B1 genetic testing can confirm the diagnosis. Acting early means considering AM behind recurrent, multi-system presentations rather than treating each in turn.

Transform Lives

An approved enzyme replacement therapy addresses the non-neurological features of AM — supporting immune function, hearing, and physical capacity — with the strongest gains when treatment starts early. Ongoing multidisciplinary monitoring across ENT, immunology, orthopedics, and neurology shapes long-term outcomes.
